Hi Naki,

Just the post I was looking for. I'm looking at moving a cruise control set up from a 91 to a 93. Are the only differences the plug connectors?

Ah, some parts will fit, others won’t.

The brake pedal switches are totally different.
Blanking plug and trip computer with speed control switch has a different plug, but not sure if the wiring colours differ too.

The other parts are the same (ECU/ compressor/ bellows, dump valve, hose)

My advice? Just get the correct parts to begin with. More trouble than it’s worth trying to convert incorrect parts.

Your pictures were invaluable to me as I've just fitted my cruise control kit to my 91 XJ40 3.2.

If it's any assistance to anyone else here's my pics of conversion with some minor differences to your 93.

The original space for the dump valve and air pump in the LH front wing with the air box removed:
Image

You can see the 5 protective sleeves over the mounting studs, and the connectors (large white one and the smaller black one below):
Image

Here's the throttle linkage and note the bracket on the left that will hold the bellows and the fuel pipe clamp:
Image
Image

Because the fuel clamp can't fit on the end of the bellows stud it the clamp and screw were attached to the LH (smaller) hole :
Image

Air pump installed:
Image

Dump valve installed, note connector in clip:

First stage completed:

Glad to be of help.
It’s a very satisfying upgrade, and totally DIY.
Having cruise, is sometimes the only way to stay within the speed limit! A necessary thing in this day and are.

Next stage, the brake switch. How hard could this be?! This is one of the differences to Naki's 93 fit. This switch is fitted to a plate which is held by 2 studs which are at the top of the plate by the brake pedal hinge :
Image

The two nuts on the studs are accessed from the engine bay (just below the rubber bung). Installing the replacement switch is very tricky trying to locate the studs in the holes blindly - persistence pays off ... eventually:
Image

As an interesting comparison I photographed the std and cruise control brake switched back to back - std has two switches, cruise control one has three switches:
Image

Both use the same connectors (one yellow, one black/white):
Image

Brake switch done.

Console upgrade next.

First release three console plugs green (LH) and brown and black (RH):
Image
Image

Remove the instrument binnacle and console by removing the two bolts either side (but beware the LH rear one has an additional nut on the end holding a stay that goes off into the centre console):
Image
Image

Then release the two black connector blocks on the back of the instrument binnacle, seen here (after the binnacle had been removed):
Image

To remove the binnacle it needs to be separated from the console panel, two screws either side (holes in console panel shown here):
Image
Image

I also had to remove what looked like a security sensor from the (LH) back of the console panel held on by two nuts (seen here with Adjustment label):
Image

After the removing the light control board from the original console and installing on the replacement console (already with cruise control board and switches installed) the console was installed in reverse order of the removal (all plugs were the same):
Image

Console done.

Last stage, the cruise control module.

Having removed the passenger lower dash panel, thankfully the space for the module was still vacant with the required white plug and the small black plug right to the RH of it:
Image

Installed, I then wondered where the shorting plug is supposed to go (held in my fingers at the bottom of the picture below). I searched the wiring looms intensely but could see no suitable socket:
Image

Otherwise, this stage and the whole job was done.

Impatient to wait to find the location for the shorting plug I test drove it.

Unfortunately, it didn't work. There are no lights on the RH console (for the trip computer or cruise control) and failed to hold any speed; tried at 40-70 mph. (The trip computer functions as normal.)

So, does the shorting plug stop it from functioning?
Where does it fit?
Why do I have no lights on that side of the console? (the lights on the trip computer of the original console did work, so wiring to plug is ok)

Any help, greatly appreciated.

IIRC it goes somewhere under the driver's knee bolster - but it was a long time ago...

Maybe trip module lamps are blown in in replacement console and another fault is preventing the speed control from powering up (shorting plug perhaps like you say)?
